Get the The Jones Theory mug.
This theory becomes manifest when, during a conversation with another, apparently socialized north american inhabitant, it is realized that one of the two interlocutors is somehow unaware of a concept or topic that all such socialized people know, such as being familiar with the entertainer Tom Jones. The theory is predicated on the potential for someone to simply never encounter the concept or topic while otherwise having full social intergration.
Kevin: "So, you're telling me that you've never heard of 'The Eagles'? They are like one of the most popular bands of the last thirty years. Man, that's some serious Tom Jones Theory action there."

David: "No. Never heard of them. Is their music good?"

Kevin: "Not at all, but that's not the point."
